一.规矩动词(Regullar Verbs) 的曩昔式由“动词本相+ed”组成,具体变更有：
1. 一般的直接在词尾加ed.如: want—wanted, work—worked, need—needed,
clean—cleaned
2. 以不发音的e结尾的在词尾加d.如：like—liked, live—lived, use—used, move—moved smilesmiled; hopehoped.
留意：ie结尾动词,直接加d: died;tied.
3. 以一个元音字母加一个子音字母结尾的重读闭音节动词,先双写结尾的子音字母,再加ed.如：stop—stopped, trip—tripped
planned;
4. 以子音字母加y结尾的动词,先把y变成i,再加ed.如：study—studied, carry—carried, hurry—hurried, marry—marriedworried;studied.
留意：规矩动词曩昔式加“ed”后的发音规矩：
在浊子音和元音后面 [d]
called [kɔ:ld] borrowed[bɒrəʊd] moved[mu:vd]
在清子音后面 [t]helped[helpt]passed[pa:st]
